Substitute Part Grouping Explanation

Substitution eligibility for the CDEP134-4R8MC is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 4.8 µH
• Inductance tolerance: ±20%
• Current rating: 7.5 A minimum
• Saturation current (Isat): 9.3 A minimum
• DC resistance: 12 mOhm maximum
• Core material: Ferrite
• Shielding: Shielded configuration

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Physical footprint: 13.50 mm × 13.50 mm
• Maximum seated height: 5.00 mm
• Package classification: Nonstandard

Environmental & Compliance Criteria:

• Operating temperature range: -40°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all electrical, mechanical, and environmental parameters are classified as direct substitutes. Packaging format differences (tape & reel versus bulk) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-4R8MC is a direct functional equivalent to the obsolete CDEP134-4R8MC. Both parts share identical electrical specifications, mechanical dimensions, and environmental operating parameters. The substitute part is manufactured by the same supplier within the same product series.

Key Selection Factors:

Product Status: The CDEP134NP-4R8MC carries active product status, ensuring ongoing availability and manufacturing support. The main part is classified as obsolete, making the substitute the appropriate choice for new designs and ongoing production.

Compliance Status: The CDEP134NP-4R8MC meets ROHS3 compliance requirements, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the substitute part satisfies regulatory obligations.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, standard for automated assembly operations. The main part packaging format is not specified as tape & reel. This difference does not affect electrical or mechanical performance but may impact procurement and assembly workflow.

Inventory & Supply: The substitute part maintains higher inventory levels (1357 pcs) compared to the main part (961 pcs), supporting consistent supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-4R8MC be used as a direct replacement for CDEP134-4R8MC in existing designs?

A: Yes. The CDEP134NP-4R8MC meets all electrical and mechanical specifications of the CDEP134-4R8MC. Both parts are identical in inductance value, current rating, DC resistance, core material, shielding configuration, physical dimensions, and operating temperature range. The substitute part is suitable for direct board-level replacement without circuit modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certification. The CDEP134-4R8MC is obsolete and RoHS non-compliant. The CDEP134NP-4R8MC is an active product with ROHS3 compliance. Both parts are manufactured by Sumida America Components Inc. within the CDEP134 series and share identical functional specifications.

Q: Does the Tape & Reel packaging of CDEP134NP-4R8MC affect performance?

A: No. Packaging format (Tape & Reel versus bulk) is a supply and assembly consideration only. It does not affect electrical performance, mechanical fit, or functional characteristics. Tape & Reel format is standard for automated surface mount assembly operations.

Q: Are there any compliance or certification differences between these parts?

A: Yes. The CDEP134NP-4R8MC is ROHS3 compliant, while the CDEP134-4R8MC is RoHS non-compliant. Both parts carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications. The substitute part is suitable for applications requiring RoHS compliance.

Q: What is the current saturation rating, and why is it important?

A: Both parts have a saturation current (Isat) of 9.3 A. This represents the current level at which the inductor begins to lose inductance due to core saturation. The 7.5 A continuous current rating provides a 1.24 A margin below saturation, ensuring stable performance under rated operating conditions.

Q: Can these inductors be used in high-frequency applications?

A: The inductance value is specified at 100 kHz test frequency. These components are suitable for applications operating at or near this frequency. Self-resonant frequency data is not provided in the specifications; applications requiring operation significantly above 100 kHz require additional frequency response characterization.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating have unlimited shelf life under normal storage conditions and do not require special moisture control during handling, storage, or assembly. No baking or desiccant packaging is required.
